The research on the diagnostic accuracy of Spanish language depression-screening instruments continues to be scarce in the US. Under-detection of depression by Primary Care Providers is approximately 50 % in the general population and this rate may be even higher for Latino immigrants for whom the depression rate tends to be higher than for non-Hispanic Whites. This systematic review shows that there is still limited evidence that guides primary care-based depression screening for Spanish speakers. The economic, social, and human costs of depression are high and complex; yet improvements in the effectiveness of treatment cannot be made available to sufferers of the disorder if they go undetected.
